Federal prosecutors say law enforcement officers discovered the marijuana-growing operation last October on five acres of the Big Muddy National Fish and Wildlife Refuge in Howard County. That’s where Vasquez-Duarte and Reyes were arrested.

Prosecutors say a U.S. Fish & Wildlife Service agent calculated that there were 881 plants in the ground and 1,103 plants that had been cut and were drying at the site.

Sentencing dates for Vasquez-Duarte and Reyes were not immediately set.
